Seven people die in chaos near Kabul airport: UK
"Our sincere thoughts are with the families of the seven Afghan civilians who have sadly died in crowds in Kabul," a ministry spokesman said.
"Conditions on the ground remain extremely challenging but we are doing everything we can to manage the situation as safely and securely as possible," the spokesman said.
British Defence Secretary Ben Wallace told the UK newspaper Mail on Sunday that "no nation will be able to get everyone out" before the US deadline of 31 August.
"Perhaps the Americans will be permitted to stay longer and they will have our complete support if they do," he said.
